PATENT OFFICE TREVOR R. GAUTIER, .OF NASHUA, NEW HAMPSHIRE, ASSIGNOB T NASHUA GUMHED AND COATED PAPER COMPANY, OF NASEUA, NEW HAMPSHIRE, A CORPORATION OF MAssncnusEr-rs COATING-APPLYING DEVIGE Application filed September 13, 1926. Serial No. 185,062.

My invention aims to provide improved means for moistening adhesive or gummed stickers, labels, sealing tape or strips, or other like adhesive material or for-applying adhesive to similar but ungummed material.

In the accompanying drawings illustrating by way of example one form of the invention :.7 r t t 1 is a side elevation of a moistening device embodying my invention; and

Fig. 2 is a vertical, longitudinal section thereof.

Referring more particularly to the drawings the illustrative device shown includes a receptacle or container, such as the tank or reservoir 1, having a suitable'base,herein including the lugs 2, 2, whereby the device may rest upon any suitable surface when it it to be used alone, or may be received in strip serving apparatus of any desired type for use in conjunction therewith.

In the reservoir is an inverted Wick, brush, or moistening element 3 having yieldable hairs or bristles of a length to project above jacent edges.

dill

sure member or bar, flap, or resser plate 7 the reservoir while the lower portion of the brush is submerged in the liquid therein, whereby moisture will be conducted, by capillary action, to the exposed upper portion of the brush. The top of the reservoir includes a forwardportion 4, and a rear portion 5 spaced sufficiently therefrom to permit the brush to project upwardly between their adproper position in the reservoir, preferably 7 removably, and desirably at somewhat of an inclination to the vertical, by any suitable means, such as the opposed airs of ribs 6, 6 on the inner side walls 0 the reservoir, cooperating with said portions 4 and 5. The adjacent bottom portions of the reservoir may be inclined, as indicated at 6*, to assist in positioning the brush. 7

The adhesive strip or tape to be moistened is guided in cooperative relation to the moistener or brush 3. Herein, for the purpose stated, the upper wall portion 5 of the reservoir provides a guide, the strip to be moistened passing between said guide and an overlying weight, presser, guide, platen, pres- The brush may be held in the forward portion of which rests yieldably upon the upper portion of the brush 3. Said presser 7 is hingedly or pivotally supported or mounted for movement toward and away from the brush, as by means of the fingers 8 on said plate, having recessed lower edges so as to seat pivotally upon a bar or cross piece 9 on the reservoir and spaced from it sufliciently to permit passage of the strip to be moistened. By reason of said construcwhereb the moistening couple is self adjusting an the ressure on the brush moistener,

the hairs or ristles of which provide multiplex contact means, is kept substantially constant and ad usted-to any possible irregularities in the thickness of the strip or tape, or

to wear of or varying position of the brush. The presser and reservoir are formed to insure proper reception and guiding of the adhesive material to be moistened up to and across the exposedbristles or hairs of the brush, andfor this purpose the under surface of the presser and the adjacent upper guide surface of the reservoir are inclined, as indicated at 10, llres pectively, whereby said surfaces are substantially parallel to the defl sired path of the strip or tape, which will be passed accurately to and between the presser and brush, the 'latter acting'substantially as a continuation of said guide. Said presser is formed and proportioned-to aifprd proper and uniform moistening contact of the strip' 'or tape and the brush, the presser' being suitably weighted, if desired, as indicated at 12.

As above mentioned, however, the presser is readily yieldable upwardly, or away from, the brush, permitting easy passage of the strip or tape.

It will be noted that the presser may ease be lifted to afiord access to the brush,

or may equally readily be bodily removed for cleaning or inspection purposes. To assist in proper ositioning of the presser with respect to the brush when the presser is lowered or replaced after such lifting or removal, or at other times, or to prevent excessive pressure on'the moistener I may pro,- vide suitable means such as the stops or screws 13, 13 adjustable by increments of any desiredextent, including extremely fine adjustments, in the respective ears 14 on the reservoir. Said adjustable stops underlie the presser so as to prevent undue downward movement thereof, and'serve to govern its angular position. I

The cover or top of the reservoir may be either removable or integral as desired, and

' filling means such as the lip 15 and cooperating opening in the adjacent wall of the reservoir may be provided, said lip, as illus- .trated, also providing a convenient means for grasping the reservoir for removing it from its osition in a stri serving apparatus.

y invention is not imited to the particular embodiment thereof herein shown and de scribed, its scope being set forth in the appended claims.

Claims:

1. Mechanism for moistening adhesive or gummed strips, tapes, labels or the like com prising a reservoir, a brush moistener in said reservoir, a plate or guide to direct the material to be moistened to and across the brush in moistening contact with the projecting bristles thereof, said plate or guide having a pivotal support permitting it to yield away from the brush and to be lifted for cleaning or inspection purposes, and a plate engaging member on the reservoir, having threaded engagement with a portion thereof whereby said member is vertically adjustable with respect to the reservoir by-inerements of any desired extent, includingextremely fine increments, said member underlying said plate properly and positively to position the same when it is lowered or replaced after lifting or removal or to prevent undue pressure of said plate upon the brush.

2. In a device for applying a liquid coating to strip material, a reservoir for the liquid, a brush in the reservoir with the free ends of its hairs or bristles projecting above the liquid level, a presser plate having a portion overlying the brush, a stationary strip or bar extend ng transversely of the path of the strip material and above the reservoir said strip or bar having its upper edge forme to constitute a fulcrum, and means on the presser plate provided with a downwardlyopenin formation for receiving said upperedge 0 said strip or bar in a manner permitting vertical pivotal movement of the plate and also permitting complete bodily removal thereof at ahy time. 3. Means for moi su P p strip and adapted .for use alone or in conjunction with strip serving mech'anism, comprising, in combination, a liquid receptacle 1 aving a base upon which it is adapted to stand upright, a rush 3 set in the receptacle with the free ends of its hairs or bristles projecting above the highest liquid level, supporting means 6, 6 in the receptacle for removably holding the brush in said position, guide means 5, 11 on the receptacle for cooperation with the under face of the strip to conduct the latter to and upwardly across the projecting end of the brush, a downwardlypressing platen 7 overlying said guide means and brush and cooperating therewith to conduct the strip in moistening relation with the brush, a cross-piece 9 associated with the reservoir, spaced rearwardlyfrom the projecting portion of the brushand arranged to permit the strip to be passed beneath the cross-piece, one or more rearwardly extending fingers 8 having downwardly-open bearing recesses adapted to be engaged with said cross-piece 9 whereby the latter provides a pivotal support for the platen 7 while enabling the platen to be removed bodily from its operative position without manipulation of other parts, and means 13, 14 for adjusting the platen relatively to the brush.

In testimony whereof, I have signed my name to this specification.
